INTRODUCTION 



Ants are very highly developed social animal 
and have got a specialised colonial habit with 
marked degree of division of labour amongsts its 
various constituent casts, They are the premier soil 
turner, channelers of energy, dominatories of the 
insect world and represent the culmination of insect 
evolution in the same sense that human beings 



then, this tiny creature has remained totally 
neglected by the biologist. 

About one-third of entire animal biomass of 
Amazanian rain forest is composed of ants and 
termites. These two kinds of insects along with 
wasps and bees, cover 75% of the total insect 
biomass (Holldobler and Wilson, 1990). 

While density of ants is so much so, in the 
insect biomass, it is the prime duty of a 
Myrmecologist to assess the distribution of ants in 
its own continent. Southern India being the 
peninsular part of the country, carries more 
importance because of possession of tropical forests 
which provide the suitable environment for the 
growth of insect fauna. The present work is an 
endevour by the author to contribute to the 
knowledge of ant fauna of Southern India. 

Jerdon ( 1 85 1 ) worked on Indian ants particularly 
from Southern India and recorded 46 species under 
8 genera from this region; of these, 39 species 
were new to science. Later on, Rothneyi (1889), 
Forel (1900), Donisthorpe (1942, 1943) contributed 
much to the ant fauna of Southern India. Prior to 
this, Bingham (1903) published his valuable work 
on the Ant Fauna of British India, including Burma 
and Ceylon and gave detailed account of 
distribution of the species recorded. 

Sucessive workers like Forel (1900a, 1900b, 
1 900c), Mukherjee ( 1 927), Karawajew ( 1 926, 1 927, 
1928), Wheeler (1927, 1928), Menozzi (1935), 
Donisthorpe (1942a, 1942b, 1942c, 1943), Smith 
(1948), Brown Jr. (1954, 1957, 1959a), Wilson 
(1964), Taylor (1965, 1966, 1968), Collingwood 
(1970), Bolton (1977), Baroni Urbani (1977a, 



1977b), Tiwari etal. (1977a, 1977b, 1977c, 1986a, 
1986b, 1994a, 1994b, 1996, 1997) and Imai etal. 
(1984) have made valuable contributions to the ant 
fauna of India, but no one has exclusively studied 
the ant fauna of Southern India. There have been 
some records of ants from various parts of Southern 
India in scattered form. This is the first attempt by 
the present author to consolidate the ant fauna of 
Southern India. 

The present work is based on a collection of 
ants from Tamil Nadu, a part of Kerala (coll. O.B. 
Chhotani.and R. N. Tiwari in Feb.-March, 1969), 
Andhra Pradesh (coll. J. N. Maligi in 1962 and N. 
M. Antony in 1969). Besides this the species 
recorded from Southern India, lying in National 
Zoological Collection of this department 
(Zoological Survey of India), have also been 
incorporated. The entire material studied under 
this project, have been deposited in the collection 
of Zoological Survey of India, Calcutta. 

Altogether 2 1 9 species under 48 genera and 7 
subfamilies have been reported in this monograph. 
Out of these, 22 species are reported for the first 
time from Southern India and 2 species are new 
records from India. This includes descriptions of 
Worker and Female of 1 new species along with a 
new description of Female of 1 known species 
separately. The taxa marked with single asterisk 
(*) in "the list of Taxa in Systematic Account" are 
new records from the states of Southern India and 
those marked with double asterisks (**) are new 
records from India. 

Key to the subfamilies, genera and species, 
include only those species which were studied by 
the author. The species, recorded from literature, 
have been omitted in "Key to the species" because 
of insufficient description and non-availability of 
concerned papers. The separate Table showing the 
distributional pattern of recorded species zone- 
wise, along with distributional analysis of the 
same is also provided to have a glimpse of the 
distribution of the species at a glance. The mode 
of arrangement of the species is followed as in

Southern India or the Indian peninsula is 
bounded by Bay of Bengal in the east, the Arabian 
sea on the west, the Indian Ocean on the south and 
Satpura and Vindhya ranges in the north. The 
farthest point in the south is Kanyakumari, which 
lies at 804' N latitude and 7736' E longitude. 
The peninsula has Western Ghats on the west, 
which rising steeply from the narrow costal plains, 
reach to greater heights of more than 1,200 m 
above mean sea level in certain parts and to more 
than 2,000 m in the south in Nilgiris, the Anaimalai 
and Cardamon Hills, the highest peak being at an 
altitude of 2,695 m above mean sea level in the 
Anaimalai Hills. The general slope of the land is 
towards the east, and such as, the Eastern Ghats 
are much lower than the mountains on the western 
side. The Deccan plateau lies at the centre and is 
generally 300 m high, rising to more than 600 m 
in Southern Deccan. On the east are wide eastern 
coastal plains with the high Shevaroy, Javadi and 
Pachaimalai Hills. 

The western coastal plains have numerous short 
and rapid flowing streams, some forming lagoons, 
a characteristic feature of the Malabar coast. The 
caster plains below 16 N, have only one large 
river of importance, the Kaveri, and a few small 
ones, the Penner, the Palar and the Vagai. These 
are also fairly fast flowing as they flow towards 
the sloping plateau. All these rivers are seasonal 
and depend entirely on the monsoon rains. 

The peninsula has been a stable land-mass 
since the very ancient times, at least the pre- 
cambrian and consists of highly metamorphosed 
rocks like gneisses and schists of the Archaean- 
system. The deltas in Tamil Nadu and Kerala 
states are alluvial. The Deccan lavas, some rocks 
in Tamil Nadu and parts of Coromandel plains 
have regur soils, while the major portion of the 
peninsula has red soil found on the Archaean 
crystaline rocks. 



Southern India has a fairly hot climate. The 
hottest months are April-May, when the maximum 
temperature varies from 32C-40C in different 
parts. The coldest months are December-January, 
when the maximum temperature varies from 27C- 
30C. The Malabar coast has fairly uniform 
temperature during the year varying 28C-32C, 
in Deccan between 30C-40C and in the south- 
east between 29C-37C. 

Both south-east and south-west monsoons are 
active in Southern India. The south-west monsoon 
is more active, giving heavy rains in the Malabar 
coast and Western Ghats and little in Deccan and 
eastern coast. The north-east monsoon gives rain 
in the eastern coastal areas. The average annual 
rainfall is more than 2,500 mm in Malabar coast 
and Western Ghats, about 900 mm in Karnataka 
and south-east Tamil Nadu and about 600 mm in 
Deccan. 

Western Ghats being very wet, have tropical 
evergreen forests. On the eastern side of these 
Ghats are found dry deciduous hill forests and 
some sub-tropical evergreen forests in the Shevaroy 
Hills. 

MORPHOLOGY 

Morphologically ants are at once distinguished 
from other aculeate Hymenoptera by a remarkable 
modification of the one or two segments of the 
abdomen immediately following the median 
segment or propodeum. This modification of the 
anterior portion of the abdomen consists in the 
almost complete detachment of one or two 
segments from the rest of the abdomen to form a 
highly flexible pedicel composed of one or two 
nodes. In the majority of the genera of the family 
Formicidae, the attachment of the pedicel to the 
median segment in front and to the rest of the 
abdomen behind is extremely constricted and 
narrow, giving great freedom of movement to 
both thorax and abdomen properly. When the 
pedicel is formed of two segments, a similar 
constriction lies between the two. In certain low 
forms of primitive ants like Myopopone, 
Amblyopone, etc., the node of pedicel is attached 
by the whole of its posterior face to the succeeding 



TIWARI : Taxonomic Studies on Ants of Southern India 

segment of the abdomen, showing an 
approximation to the stiffer and more ponderous 
form of abdomen possessed by fossorial wasps of 
the family Scoliidae. 

Ants like other social Hymenopterans, such as 
Honey-bees and wasps, exhibit the maximum 
degree of social pattern and thus are differentiated 
into following forms : 

1 . The female or perfect fertile female 9 

2. The male cf 

3. The worker or so called Neuter ? 

The workers are undeveloped female and are 
invariably wingless and generally have the thorax 
more or less modified and different from the 
thorax of male or female. On shape and size, they 
are further differentiated into : 

(a) Worker minor ? min. 

(b) Worker major $ maj. 

Further some of the workers are especially 
modified in their morphology for the purpose of 
fighting and protecting the colony from external 
invasion. For this purpose, their mandibles are 
strong and stout and have got bigger head. They 
are called Soldiers (3|). They are further 
differentiated according to the size as follows : 

(a) Soldiers minor 2| min. 

(b) Soldiers major 2| maj. 

The parts of the head, thorax and abdomen in 
an ant are homologous with those in other 
Hymenopterous insects, but are generally modified. 
The given figures (Figs. 1-4), illustrations of some 
of the various parts assumed by these, with details 
of the parts of which they are composed. The 
lettering in all the figures is alike and refers to the 
same parts (Bingham, 1903). 

TERMINOLOGY 
Mouth parts 

Mandible : The various parts of mandible are 
shown in Fig. Ib. The most distal tooth is termed 
the apical, and the rests are sub-apical teeth; 
dental formulae are coded in the form "1 + 3", 
indicating one apical and three sub-apical. 

The basal shaft of the mandible bears several 
characters of classificatory importance. The 



mandalus is a small, unpigmented, apparently 
membranous lacuna which may contain the orifice 
of the duct from the mandibular gland. In shape, 
the mandalus may be linear, key-hole shaped or 
even triangular (Fig. Ib). 

Trulleum : Distal to the mandalus is a large, more 
or less basin shaped depression called Trulleum, 
bounded 'laterally and distally by the blade of the 
mandible and medially by Canthallus (Fig. Ib). 

Canthallus : It is a raised ridge running distal 
from the base of the mandible (Fig. Ib). 

Labrum : The labrum (Fig. 2F) is movably 
articulated below the median area of the clypeus 
and folds up under the closed mandibles, forming 
with the exposed plates of the labio-maxillary 
complex, a tight seal over more delicate mouth 
parts and buccal opening. 

Maxillary and labial palpi : The palpal formula 
is a valuable character in identification. The old 
palpal formula is out dated and not in practice 
(Fig. 2E-F). 

A variable amount of fusion between segments 
which can not be seen in dried material is clear in 
immersed preparation (Kusnezov, 1954a, 1954b). 
As this fusion is important for phylogenetic 
reasoning the palpal formula is coded in a way, 
that indicates three degree of fusion, 
i. Separate segment or s 
ii. Partial fusion or p 
iii. Complete fusion or c 

"4, 3" represents four freely articulated maxillary 
segments and three freely articulated labial 
segments. 

Body Parts 

Thorax : The thorax of ants varies enormously in 
shape and development of the component parts. 
The thorax of a worker (?) differs markedly from 
the thorax of female (9) or male (C?) of the same 
species. 

The thorax of ants of different subfamilies, 
vary greatly in the structures and as such no 
typical diagram of an ant serves the purpose. 
However, in order to give different body structures, 
Solenopsis sp. has been selected as a typical form 



Memoirs of the Zoological Survey of India 



and the terms related to identification have been 
elaborately illustrated in Figure Id. 

Wing : To the mesothorax at the sides above are 
attached in the female (9) and male (cf), the fore- 
wing, and to the sides of the metathorax, the hind- 
wings, the nerve venations of the wings are less 
complete than in most of the Aculeata. ' 

In the fore-wing the radial, coastal, medial and 
two sub-medial cells are always complete; others 
are variable and may or may not be present, 
complete or incomplete (Figs. Ic, 3A, B, D). 

Legs : Three pairs of legs are present in all sexes 
containing the following parts : 

Coxae, trochanter, single jointed femora, tibiae, 
tibial calcaria, which may or may not be present 
on all the legs, are often double, and may be 
pectinate or simple; tarsi 5 joints, the apical joint 
armed with two claws, which may be pectinate, 
dentate or simple (Figs. 3E-G). 

Abdomen : The abdomen in worker (?) and 
female (9) is composed of 6 segments, in the male 
(C?) of 7 visible segments and is like the rest of the 
parts in ants, very variable, generally more massive 
and comparatively longer in the female; smallar 
and more slender in the male than in the female 
(Figs. 4A-E). 

Other Terms 

(Figs, la-d) 

Inferior propodeal plates : These are pair of 
flanges or plate like structures placed vertically on 
either side of the foramen of petiole. (Synonymous 
terms are "lamellae", "rounded lamella", 
"metapleural lobes" and "meta-sternal lobes"- 
keml). 

Levator foramen : It is a partially separated 
channel in the roof of the propodeal foramen, into 
which fits a ligament that elavates the petiole. 

Median meta-sternal process : It is heavily 
sclerotised and consists of longitudinal grooved 
extension of the metasternum and is meant to 
receive the sub-petiolar process of the petiole. 



Median meso-sternal process : It is ventral ly 
and posteriorly directed elaboration of the anterior 
margin of the mesonotum, its function is unknown. 

Sub-petiolar process : It is a structure originating 
from the ventral surface of the petiole. It consists 
of 2 ridges, 1 ) an anterior ventral transverse ridge, 
and 2) posterior ventral transverse ridge which is 
actually an elaboration of the posterior sternal 
margin of the post-petiolar segment. 

The post-petiole articulates by a ball and socket 
joint with the gaster (or abdomen) the "Ball" of 
the gaster generally being concealed within the 
"socket" of the post-petiole. 

SYSTEMATIC ACCOUNT 

Formicidae is one of the largest family of order 



distributed throughout the world, because of its 
cosmopoliton nature. 9538 species of ants under 
16 subfamilies, 59 tribes and 296 genera have 
been reported till date from the world (HoIIdobler 
and Wilson, 1990). The most speciose subfamilies 
are Myrmicinae (4377 species, 155 genera), 
Formicinae (2458 species, 49 genera), Ponerinae 
(1299 species, 42 genera), Dolichoderinae (554 
species, 22 genera), Pseudomyrmecinae (197 
species, 3 genera). Subfamily Myrmicinae 
represents 45.89% of the species and 52.34% of 
the genera of the world, whereas Formicinae 
represents 25.77% of the species and 16.55% of 
the genera. Similarly Ponerinae represents 13.62% 
of the species and 14.19% of the genera of the 
world (Bolton, 1995). 

From Oriental region (including Indo- 
Australian), altogether 227 genera of ants have 
been reported till date, of these 27 genera are 
endemic in nature. The number of species described 
from Oriental region is 2480 (the splited number 
being 771 from Oriental region and 1709 from 
Indo-Australian region). 

Prior to this, Bingham (1903) reported 498 
species under 79 genera from India, including 
Burma and Ceylon. Subsequently, Chapman and 
Capco (1951) recorded 2080 species, 441 
subspecies and 684 varieties oi cjiis spread over 
176 genera in their check list from Asian 
subcontinent.

I. Subfamily DORYLINAE Forel 

Members of this subfamily are known as army 
ants and are sometimes referred to as legionary 
ants in the New World and Old World. They are 
predaceous and are known for their foraging 
expeditions, the size of which are sometimes 
exaggerated. Army ants exhibit a number of 
morphological and biological peculiarities not 
common to most ants, such as, wasp-like males, 
wingless termite-like females, blind workers, and 
their raiding and emigrating behaviour. Retten 
Meyer (1963) outlined the following traits in which 
they differ from other ants : 1) they feed almost 
exclusively'on animal prey which is collected by 
large groups raiding workers; 2) their raiding 
columns usually connect to the nest by at least one 
continuous column; 3) the entire colony periodically 
and frequently emigrates to new nest's sites ; 4) 
emigration are largely dependant on the size, cast, 
age and range of ages of the brood (or broods); 
and 5) the colonies are founded by division of an 
entire colony into two (or possibly several daughter 
colonies. Other ants may possess some of these 
traits, but not all of them. 



Memoirs of the Zoological Survey of India 



Much of the biological work on army ants has 
been done in Central America on the terrestrial 
species of Eciton which are found in large clusters 
above the ground and whose colonies may number 
upto million individuals. Most of the army ants, 
however, are sub-terranean in habit, though the 
raiding columns of some may appear above ground. 
Raiding may be in columns only several ants wide 
or in swarms of a fan-shaped pattern. Most of the 
prey is other arthropods, only occasionally 
vertebrates. All species have nomadic and statary 
activity cycles where the entire colony moves 
from one area to another, a unique behaviour 
exhibited by this group. 

Most of the taxonomy is based on males and 
workers, and for some species only one caste is 
known.

Biological notes : This species is commonly known 
as root-eating ant, the workers feed on soft parts 
of roots and the tuberous roots are hollowed out. 

Green (1903) also agreed with above vegetation 
behaviour of the said species. But Mukherjee (1933) 
doubted this. He studied the worker's mouth parts 
in details and found them "better adapted for 
feeding on animal food than on plants. The 
mandible is similar to that of the species Dorylus 
(Typhlopone) labiatus Shuck., 1840, which is 
carnivorous in habit. The sharp-pointed bristles, 
spines and setae on the 1 st and 2nd maxillae, can 
well pierce the skin of the victim and draw out the 
nutritive fluid from the body of their prey, which 
they suck by their a mobile tongue." 

The male resembles wasps and females are 
wingless and blind. In Southern India only one 
male was collected at light no workers came 
across, evidently it is presumed that it is not very 
common species in Southern India.

II. Subfamily PONERINAE Lepeletier 

The species of this subfamily are primarily 
characterised by a constriction, sometimes slight 
but generally distinct, and often remarkably deep, 
between the basal two segments, and by the 
unmodified powerful and generally exerted sting. 
The body more or less elongate and cylindrical, 
the abdomen especially so; the mandibles powerful; 
the antennae more or less ma c sive; eyes generally 
present, absent in one or iwi genera; legs 
moderately long. Habits predaceous and 
carnivorous. The Ponerine ants carry their prey or 



TIWARI : Taxonoir 



t'ood underneath the body between the fore legs, a 
method of carrying food, quite different from that 
adopted by the Camponotinue and Myrmicinae. 
The males and females of Ponerinae, so far as they 
are known, are always winged. This subfamily 
mostly represents the primitive group of ants and 
thus can be treated as the ancestral stock in the 
phylogeny of ants, The nests, in small colonies of 
a few hundred individuals or less, mostly on soil 
or rotten wood. They are abundantly distributed 
all over the tropical regions of the world, but are 
even reported from some European and American 
countries and the cause of this migration is the 
introduction of commerce from one part of the 
world to the other.

III. Subfamily CERAPACHYINAE Forel 

This small subfamily, found in the tropical 
regions of the world, exhibits a blending of doryline 
and ponerine traits both morphologically and 
biologically. Little is known concerning the 
behaviour, but they are predaceous and carnivorous 
and the colonies are small. Wilson (1959) studied 
the behaviour of several species from Melanesia 
and Australia and found them all to be 
myrmecophagous, feeding on the broods and 
sometimes adults of other species of ants. He (op. 
dt.) suggested that these ants carry on an alternating 
group foraging and raiding behaviour pattern by 
which the colony efficiently exploits the 
surrounding territory. 

However, Brown (1976) does not recognise 
this subfamily Cerapachyinae and is of opinion 
that the two tribes Cerapachyini and 
Acanthostichini should be treated as the tribes of 
subfamily Ponerinae.

IV. Subfamily PSEUDOMYRMECINAE Emery 

This is a small subfamily with one genus in the 
New World and several genera in the Old World 
tropics. Smith (1951) named the subfamily 
Leptaleinae based on the genus Leptalea Erichson 
but later on, he (1952) found an earlier generic 
name Pseudomyrmex Lund, and changed the 
subfamily name to Pseudomyrmecinae which has 
become widely established. The species of this 
subfamily are most virulent, the sting being most 
painful and sometimes causing considerable 
inflammation. They are arborial in nature. They 
make their nests in the dead wood of trees and 
very often, in the clefts of the beams and posts of 
wooden houses. By habit , they are feroceous in

nature, particularly Tetraponera rufonigra is called 
'Lohari' in Northern India, meaning the Black- 
smith, this name has been given because of it's 
fierce nature.

Remarks : Forel (1902) did not give the exact 
locality while describing this species. Bingham 
(1903), however, recorded it from Western India 
and Ceylon with some doubt. He (op. cit.) also 
noted that he had two specimens from Sri Lanka 
(formerly Ceylon) and thought them to belong to 
a variety of aitkeni as they differed from Forel' s 

(1902) original description of the species aitkeni 
in some characters. The present specimens from 
Southern India, collected from coconut trees, come 
to aitkeni Forel when run through Bingham' s 

(1903) key. Emery (1921) has recorded it from 
Kanara. But subsequently, Chapman and Capco 
(1951) also reported this species from Kanara.

noted some important characters of the worker of 
this species as "Body length ll/48th of an inch; 
head oblong; eyes very large, slightly advanced; 
thorax considerably grooved, abdominal pedicel 
long, low; abdomen long, ovate, black with rufous

recorded this species under the genus Tetraponera 
(Tetraponera) in their monograph and also 
mentioned its locality as "Salem district". 



V. Subfamily MYRMICINAE Lepeletier 

This is the largest subfamily of ants and is 
found throughout the world. In phylogenetic tree, 
it stands at the top, i.e., it has adapted to the 
highest adaptation and as such the sizes have 
appreciably reduced. This subfamily can be 
distinguished from the other subfamily of the 
family Formicidae by the pedicel being distinctly 
two-jointed in all sexes. The neuters of the genus 
Aenictus also have two-jointed pedicel, but they 
are absolutely without eyes and ocelli. The antennae 
are long, thick and massive planted extremely 
close to the anterior margin of the head with their 
bases very close together. The sting in :he 
Myrmicinae is present but not often exerted, and 
the pupae are not enclosed in cocoons. No specific 
demarcation can be made for their habit and habitat, 
because they are found in almost all habitat except

Remarks : Atta providens Sykes, 1835, reported 
as type-species of pheidole from India (Bingham.

'Fauna of British India.'. However, Jerdon (1851) 
treated this species as Ocodoma providens (Sykes) 
with some doubt, but on careful analysis it is 
found that the species ought to have been treated 
as Atta providens which he (op. cit.) misplaced 
under Ocodoma. This species has been included 
separately in this paper under the genus Pheidole 
(Pheidole). The distribution of this species as 
shown by Jerdon (1851) happens to be "Southern

cit.) placed this species under the genus Myrmica 
(Cremastogaster). Subsequently, Chapman and 
Capco (i951) also treated it as a separate species 
under Crematogaster (Acrocoelid). Prior to this, 
Jerdon (1851) described this species under the 
genus Myrmica from Malabar, Kerala. He. (op. 
cit.) also mentioned, "This is a well known and 
widely diffused species, being found throughout 
India. It makes its nest in holes in branches of 
trees". 

Jerdon (1851) further mentioned "It runs with 
its abdomen turned upwards almost over its head 
especially when excited, and feeds on honey and 
other vegetable secretions. Occasionally they appear 
to join their nest among the roots of Moss, 
Orchideae, and various Epiphytic plants. It is very 
pugnacious, and bites very severely, not appearing 
to use its sting much."

species under Myrmica (Cremastogaster). 
Subsequently, Chapman and Capco (1951) also 
reported this species and mentioned its locality as 
"S. India". 

This is very closely allied species with C. 
diffusa (Jerdon, 1 85 1) and differs from diffusa by 
having larger body size, head shorter proportionally, 



thoracic spines longer and straighter, 1st abdominal 
pedicel longer but less raised (Jerdon, 1851).

from the soil along with Crematogaster rogenhoferi 
Mayr, 1878 and Solenopsis geminata (Fabricius, 
1804) at Salem (Tamil Nadu). 

Remarks : Bingham (1903 : .211) noted "Typical 
M. gracillimum, so far as I know, has been 
recorded within our limits only from Ceylon; but 
the form separated as var. mayri (Forel, Rev. 
Suisse Zool. x (1902), p. 209) is spread throughout 
India and Burma. It differs from true M. 
gracillimum in being dark brown with the 
mandibles, antennae and legs pale yellow; the 
basal portion of the metanotum is submargined 
and is more abruptly truncate at apex, it is densely 
and very finely transversely striate and opaque".

Remarks : Jerdon (1851) first described this 
species floricola under the genus .A tta from 
Tellicherry (Kerala). While describing this species, 
he also noted in the same publication that he had 
obtained this very small ant, of which he had only 
seen one kind of individual, in small numbers on 
flowers and leaves and it appeared to feed solely 
on vegetable secretions.

Remarks : Jerdon (1851) described the species 
minuta under the genus Atta from Karnataka, 
which was synonymised with M. pharaonis (Linn.) 
by Bingham (1903). Bingham (op. cit.) mentioned 
its distribution as "Throughout our limits, and 
spread over the tropical regions of both 
hemispheres". 

Jerdon (1851) further noted "this minute species 
makes a temporary nest in various situations, in 
an empty box, between the back and its leaves, 
even among the loose pages of a book, in an 
empty shell etc. Nothing is used in its construction, 
a shelter from the light merely being sought for. It 
is perhaps not very numerous in individuals, one 
wingless female is generally found in the nest. It 
appears to prefer dead animal matter to saccharine 
or vegetable products".

described this species under the genus Atta from 
Southern India and further mentioned its 
distribution as "They are common in all parts of 
India, and often prove very troublesome and 
destructive to the Naturalist". Later, while reporting 
this species under the genus Monomorium, 
Bingham (1903) noted its distribution as 
"Throughout our limits, and spread (probably 
carried and introduced by shipping) through the 
torrid regions of both hemispheres".

Distribution : INDIA ; Tamil Nadu, Kerala, 
Karnataka, West fiengal. Elsewhere ; Spread pretty 
nearly over the tropics of the two hemispheres. 

Biological notes : While describing the species 
/Ufa rufa, Jerdon (1851) noted "It is found in holes 
under gfotlttd, mud walls and often appears in 
houses, coming through a hole or crevice in the 
floor or wall. Its favourite food is dead insects 
and other matter. It stings very severely, leaving a 
burning pain that lasts for several minutes". 

According to Beeson (1941) S. geminata, 
commonly known as 'Brown Fire Ant', has a 
severe sting. It makes its nest in soil and is 
reported to be injurious to seedlings buds and 
leaves. It is reported to be an important enemy of 
aphids, soft scales, termites, bed bugs and moth 
larvae and can be introduced in the control of 
termites and catterpillars of Eublemma amabilia 
and Holococera putverea in the lac godowns. 

In Southern: India,' this ant has been collected 
from coconut and banana.plants and also from soil 
and under stones. 



Remark^ ; Jerdon ''"( l83l'j'' 'described the species 
rufa under ffiergenus '"At'ta '"frorri Malabar aria*

distribution of S. geminata (Fabr., 1804) as 
"Throughout out limits, and spread pretty nearly 
over the tropics of the two hemispheres". Further 
he (op, cit.) noted "var. rufa Jerdon is a darker 
reddish yellow". Subsequently, Chapman and 
Capco (1951) also recorded the rufa as a 
subspecies from Malabar. But Ettershank (1966) 
synonymised the species Atta rufa Jerdon, 1851 
and placed it under the species Solenopsis geminata 
(Fabricius, 1804).

Biological notes : Most of the ants of the genus 
Pheidologeton make their nests under bricks, 
stones, flower pots, rock-works, or any spot 
offering shelter or shade of this nature (Rothney, 
1889 : 369). Later on, Bingham (1903 : 161) also 
noted that nests of this group of ants can be found 
under the blocks of laterite road-material collected 
by the sides of roads repairing purpose. He had 
also found large and populous nests under stacks 
of bricks in a brickfield, under fallen logs in the 
jungle, and in the foundations of the pillars of the

wooden bunglows. He (op. dt.) further mentioned, 
"the gaint soldiers, however formidable they look, 
are absolutely unable to give even a decent nip, 
but the bites of the smaller forms of soldiers and 
of 5 min. are vicious and to be remembered. In a 
nest of these ants, the workers far outnumber the 
various forms of soldiers. So the attack of the tiny 
worker is far more ferocious and effective than 
that of the soldiers". 

Remarks : No material of this species could be 
available for this study. However, Jerdon (1851) 
first described this species from Southern India. 
Bingham (1903) also recorded this species from 
Southern India and mentioned its distribution as 
"Sikkim; Bengal; Western India, Poona, Kanara, 
Calicut, Travancore; Burma and Tenasserim. 
Extending into the Malayan subregion".

South India. 

VI. Subfamily FORMICINAE Lepeletier 

The species belonging to this subfamily are 
probably mentally and socially the most highly 
developed of all the ants. Structurally they are 
distinguished by having a one-jointed pedicel with 
no constriction between the two basal abdominal 
segments; the poison-glands and stings are 
considerably modified, the former being converted 
into a cushion of convolutions, the latter forming 
merely an orifice for the ejaculation of the poison, 
which in certain genera (Oceophylla, for instance) 
C(O\ be done with considerable force; the orifice of 
the cloaca is in this subfamily always circular, and 
ciliated round the margin. 

Certain genera of this subfamily such as 
Formica and Myrmecocystus are well known as 
slave-makers, but this habit seems confined to 
these genera in Europe, and does not so far as has 



been observed, obtain in the representatives or 
even in the same genera in India. Species of 
representative genus Camponotus of this subfamily, 
are pre-eminently known as farmers of Aphides, 
Homoptera, Lycaenid-larvae and such like 
ant-cattle.

litu synthetic substance. Some eggs were also 
found in the nest at Salem. 

This is the notorious and vicious 'Red-Ant' of 
India; it inhabits in trees and makes nest in leaves. 
Its habits have been very well described by Jerdon 
(1851), Aitken (1889), Rothney (1989), 
Wroughton (1893-94) and Green (1896, 1900). In 
Kanara and some other parts of the country, and 
through Burma and Siam, a paste made of this 
species of ant pounded is eaten as a condiment 
with curry. 

The eggs of O. smaragdina have been found to 
contain high protein, fat and as such it is used as 
a medicine to combat the condition of A- 
Vitaminosis, particularly in case of Marasemus 
condition. It is widely used for above purpose in 
tribal people and the eggs are sold in weekly- 
market for the purpose. 

Remarks : Jerdon (1851) also reported this

and noted "This ant is well known in Malabar, and 
the wooded parts of India, but is rare in the 
Carnatic, where I have only seen it in one or two 
large Mango groves". Subsequently, Bingham 
(1903) mentioned its distribution as "The whole 
of India, Burma and Ceylon within our limits, 
except the desert and treeless tracts. The range of 
this species extends through the Malayan subregion 
to Australia and New Guinea."

the pain is quite momentary. This species is 
plentiful where it occurs. It is one of the ants noted 
for tending and keeping "ant-cattle". 

Remarks : Jerdon (1851) and Donisthorpe (1943) 
also reported this species from South India under 
the genera Formica and Camponotus respectively. 
Negi et al (1930) also recorded this species under 
the genus Camponotus from Tamil Nadu (Salem).

be available for this study. However, Bingham 
(1903) recorded this species so far only from 'The 
Nilgiris'.

dry portions of the North-Western Provinces, the 
Punjab and parts of Central India. 

Remarks : The specimens of this species could 
not be available for this study. Jerdon (1851), 
while describing this species under the genus 
Formica, mentioned its habitat as "Tellicherry" of 
South India. He (op. cit.) further noted "this ant is 
found in all the forests of India living in holes in 
the ground, in tolerable numerous societies, and 
feeding on vegetable secretions".

Biological notes : The little species forms a 
temporary nest between two leaves usually, or 



sometimes in a head of flowers; It lives in small 
societies and feeds entirely on vegetable secretions 
(Jerdon, 1851). 

Remarks ! No material of this species could be 
available for this study, Jerdon (1851) described 
this speeieS from OUth India, but no specific 
legality fflentiened. Later on, Chapman and Capco 
(1*151) also mentioned its locality as "South India".

Distribution : INDIA : Karnataka. 

Biological notes : It takes up its quarters in any 
sheltered spot in a house, under a box, a stone, a 
hole in the wall, or such like places, arid when 
disturbed flits with great speed to another suitable 
spot. It's society is Vpy flUnW6u ifl individuals 
and there are many ferMles and males, sometimes 
with wittgs, at other times without wings. It feeds 
both on vegetable and animal substances (Jerdon, 
1851). 

Remarks : The material of this species could not 
be available for this study. While describing this 
species under the genus Formica from South India, 
Jerdon (1851) mentioned that this little ant was 
exceedingly common in the Karnataka. 

VII. Subfamily DOLICHODERINAE Forel 

The species belonging to this subfamily can be 
distinguished at a glance from the subfamily 
Ponerinae on the one hand by there being no 
constriction between the 1 st and 2nd segment of 
the abdomen, and on the other hand from the 
subfamily Formicinae by the anal aperture being 
transverse, and not circular nor ciliated. The head 
is short and broad; the thorax robust, the metanotum 
often compressed and raised (Dolichoderus) or 
spinous (Aneuretus); pedicel 1 -jointed, the node 
placed closer to the abdomen than to the thorax, 
sometimes inclined anteriorly, and often impinging 
on the front of the abdomen, which has a hollow 
anteriorly for its reception; abdomen generally

gibbous in front (except in Liometopurri), broadly 
oval (Dolichoderiis, Iridomyrmex)', sting not 
modified, but only in one genus (Aneuretus) 
exerted; legs slender (Aneuretus), long and robust 
(Iridomyrmex, Tapinoma), but short and stout 
(Bothriomyrmex, Technomyrmex).

the species Formica nana from Mysore, South 
India, which was later considered as a synonym of 
T. melanocephalum (Fabr., 1793) by Bingham 
(1903). Subsequently, Negi et al. (1930) also 
recorded this species from Salem Dist., Tamil

(1903) recorded this species from 'Coonoor' of 
South India. 



DISTRIBUTIONAL ANALYSIS OF THE 
SPECIES RECORDED 

Altogether 219 species of ants have been 
reported from Southern India till date. Of these, 
98 species (about 44.75%) are found to be Endemic 
in nature. Of the rest 121 species (55.25%), about 
26 species (21.49%) are found to be cosmopoliton 
and hence are widely distributed throughout India. 
Three other major zones of India, i.e., Eastern 
India, Western India and Northern India, share 
about 20 species (16.53%), 35 species (28.93%) 
and 2 species (1.65%) respectively of the non- 
endemic species. Central India, however, does not 
share any of the non-endemic species except the 
cosmopoliton species. 38 of the non-endemic 
species, comprising about 3 1 .40% are found to be 
sharing more than one major zones of India 
along with Southern India. 

The strong endemism (44.75%) indicates 
certain factors or barriers, which kept these species 
confined to Southern India only. In order to 
establish the nature of the endemism, 
zoogeographical and ecological study of the 
Endemic species is suggested. Above analysis is 
based on illustrative data in Distributional Table 
No. 1 and Figs. 10 A-B.

TIWARI : Taxonomic Studies on Ants of Southern India 

SUMMARY 

The monograph deals with the ants collected 
from several states of Southern India, viz., Andhra 
Pradesh, Kerala, Karnataka and Tamil Nadu. Main 
collection on which work is based, is from Tamil 
Nadu and Kerala. Jerdon (1851) worked 0fl Ifidiafi 
ants, particularly from Southern India and f6cefded 
46 species under 8 genera from this region. Later 
on Rothney (1889), Forel (1900a, b, c), Donisthorpe 
(1942c, 1943) contributed much to the ant fauna 
of Southern India. Bingham (1903) also made a 
significant contribution in this direction and 
recorded 498 species from this region. Although 
several workers have contributed to the knowldge 
of ant fauna of Southern India, no one has 
exclusively studied the ant fauna of this region. 

This is the first attempt by the preseilt author to 
consolidate the knowledge of ant fauna of Southern 
India. Altogether 219 species under 48 genera and 
7 subfamilies have been reported in this monograph. 
Out of these, 22 spedles Bfi reported for the first 
time from Southern India arid 2 gpggi@8 are new 
records from India. This also includes the 
descriptions of Worker and Female of a new 
species, Crematogaster pradipi sp. nov., along 



With a new description of Female of a known 
species, Cremdtogaster flava Forel, 1886 
separately. The taxa marked with single asterisk 
(*) in "the list of Taxa in Systematic Account", 
are new records from the states of Southern India 
and those marked with double asterisks (**) are 
flgw records from India. Key to the identification 
df the iAf ami lies, genera and species dealt in 
the monograph ffOffl this region have also 
been incorporated. A separate table showing 
the distributional pattern of recorded species 
zone-wise, along with distributional analysis of 
the same is also provided to have a glimpse of the 
distribution of the species at a glance. 

ACKNOWLEDGEMENTS
